Description

[Detailed Description of the Invention] The present invention relates to an improvement of a swimming cap that tightens the head circumference of the wearer by attaching an elastic tape such as a rubber tape to the lower edge of the cap body.

In the conventional swimming cap, the cap body is made of stretchable fabric knitted with polyurethane thread, etc., and an elastic tape is wound inside and sewn to the lower edge of the cap body, so that the wearer's The head was tightly tightened to prevent the cap from falling off the head while swimming, but because the elastic tape is sewn to the cap, it can be lengthened or shortened depending on the circumference of the wearer's head. It is not possible to adjust the swimming cap, and for this reason, manufacturers must prepare two or more types of swimming caps depending on the head circumference size.
In addition, there were other problems such as the user having trouble selecting a product with a head circumference that suited him or her, and the need to purchase a new product as the head circumference grows, especially in the lower grades of elementary school.

The present invention provides a swimming cap that solves the above problems. That is, the present invention provides a swimming cap in which an elastic tape such as a rubber tape is attached to the lower edge of the cap body to tighten the circumference of the wearer's head. The elastic tape (hereinafter referred to as second elastic tape) is overlapped and sewn to the elastic tape at both ends of the second elastic tape or at a position between both ends and the intermediate position thereof. The present invention will be illustrated and explained below based on embodiments.

10 is a cap body of a swimming cap made of stretchable knitted fabric; 20 is an elastic tape such as a rubber tape wrapped around the lower edge 11 of the cap body 10 and sewn 21; It is set equal to the L size, which provides a tightening force suitable for large head circumferences. Reference numeral 30 denotes a second elastic tape having elasticity such as a rubber tape, which is overlapped inside the elastic tape 20 in the length direction, and is sewn to the elastic tape 20 in the width direction at both ends 31 and 32. 320
In addition, if necessary, it is sewn 330 to the elastic tape 20 in the width direction at an intermediate position 33 between both ends (including cases where there are two or more positions). It is desirable that the second elastic tape 30 has the same degree of elasticity as the elastic tape 20 or has a smaller elongation than the elastic tape 20 when pulled with the same force.
The length of the second elastic tape 30 is determined as follows. That is, the length of the second elastic tape 30 is the same as the elastic portions 201 and 202 of the elastic tape 20 whose elongation is restricted by sewing this.
The elastic tape 20, which is the combination of the elastic tape 20 and the original elastic portion 200 of the elastic tape 20, is made equal to the S size that provides a tightening force suitable for the smallest general head circumference.

Therefore, at the time of purchase, the swimming cap of the present invention has both ends 31 and 32 of the second elastic tape 30 sewn in advance, so that the tightening force is increased and the tightening force is S-sized. Therefore, if you want L size tightening force, use the second elastic tape 3.
0 with scissors etc. cut lines 3111, 3112, 311
By cutting at points 3 and 3114, the elongation control force of the second elastic tape 30 is released, and the tightening force can be quickly and easily changed to L size.
In addition, the cutting lines 3111 and 3 of the second elastic tape 30
By cutting out either one of 112 or 3113 and 3114, it is possible to easily obtain the tightening force of M size, which is an intermediate value between S size and L size. If there are two or more intermediate positions 33 (not shown), the intermediate size between S size and L size can be further subdivided.

Another embodiment of the invention is shown in FIG. Fourth
In the embodiment shown in the figure, another elastic tape (hereinafter referred to as a second elastic tape) made of rubber tape or the like is attached in parallel to the length direction of the elastic tape 20B attached to the entire circumference of the lower edge 11B of the cap body 10B. ) multiple pieces (two pieces in the example) 30B(1) and 30B(2)
However, at both ends, 310B(1) and 320B(1) and 310B(2) and 320B(2) are sewn to the elastic tape 20B in the width direction. At this time, the length of the elastic tape 20B is such that a tightening force of L size can be obtained, and the degree of elasticity of the second elastic tapes 30B(1) and 30B(2) is plural (two in the example). In addition, it is desirable that the elongation when pulled with the same or same force as the stretch degree of the stretch tape 20B is smaller than that of the stretch tape 20B.

In addition, second elastic tapes 30B(1) and 30B(2)
The length of the elastic part 201 of the elastic tape 20B whose elongation is limited by sewing these parts is
B and the original elastic part 200 of the elastic tape 20B
The elastic tape 20B combined with B can provide a tightening force suitable for the smallest general head circumference.
It is made equal to the size.

Therefore, in this embodiment, at the time of purchase, the second
Since both ends of the elastic tapes 30B(1) and 30B(2) are sewn in advance, they have the tightening force of S size, but if you want the tightening force of M size, use the second elastic tape. One of the tapes 30
Just cut off B(1) or 30B(2) with scissors, etc. If you want L size tightening force, cut off both 30B(1) and 30B(2) of the second elastic tape. Bye. In addition, when you want a tightening force between S size and M size or between M size and L size, use the second elastic tape 30B(1).
and 30B(2) at an intermediate position (not shown) in the width direction thereof with elastic tape 20B (not shown) and handled in the same manner as the embodiment shown in FIGS. 1 to 3.

Further embodiments of the invention are shown in FIGS. 5, 6 and 7. In this embodiment, a second elastic tape such as a rubber tape having elasticity is attached to the inner side of the elastic tape 20C attached by sewing 21C over the entire circumference inside the lower edge 11C of the cap body 10C. 30C around the entire circumference of the elastic tape 20C, and at both ends 31C and 32C,
300C sewn onto 20C elastic tape in the width direction
Moreover, an elastic tape 2 is placed between the two ends.
Sewn to 0C 310C, 320C, 330C, 34
0C, 350C, 360C, 370C.
At this time, the length of the elastic tape 20C is such that a tightening force of L size can be obtained, and the length or elastic force of the second elastic tape 30C is such that when overlapped with the elastic tape 20C, the L size tightening force is obtained. It is set to the one that provides the tightening force for the size.

Then, cut the second elastic tape 30C at the cutting line 301.
C, 302C, 311C, 312C, 321C,
322C, 331C, 332C, 341C, 34
2C, 351C, 352C, 361C, 362
C, 371C, and 372C, if you cut all of them, you can get the tightening force of L size, and if you cut out a part, you can arbitrarily get the tightening force of the intermediate value between L size and S size.

As described above, according to the present invention, it is possible to change the tightening force in accordance with a change in the head circumference size very easily, quickly and reliably, and in addition, the second elastic tape is Since it is sewn on the inside, the appearance will not be affected in any way. Users no longer need to choose a size, and purchasers in the lower grades of elementary school can avoid the waste of purchasing new products as their head circumference grows. Since the manufacturer and distributor only needs to prepare one type of swimming cap, it is easy to make a manufacturing and sales plan, and the number of inventories can be reduced to improve management efficiency. In addition, manufacturing is simple, the unit price of the elongation control tape is low, and it can be mass-produced, so manufacturing costs can be greatly reduced, and quality control is easy because only one type is manufactured.
